Pin Functions

PIN DESCRIPTION
NAME NO.
GND 1 Ground pin Source terminal of low-side power NFET as well as the ground terminal for controller circuit. Connect sensitive VFB to this GND at a single point.
SW 2 Switch node connection between high-side NFET and low-side NFET.
VIN 3 Input voltage supply pin. The drain terminal of high-side power NFET.
VFB 4 Converter feedback input. Connect to output voltage with feedback resistor divider.
EN 5 Enable input control. Active high and must be pulled up to enable the device.
VBST 6 Supply input for the high-side NFET gate drive circuit. Connect 0.1 µF capacitor between VBST and SW pins.
